MESPEUS reports, for example, 13 structure where magnesium is
coordinated by a lysine. 7 with arginines and a bunch of asn/gln side
chains as well. It does not prove, of course, that primary amines
coordinate magnesium ions, only that in a limited number of cases
crystallographers have interpreted their data this way.
